To all whom it may concern:

Be it known that I, RANEY J. Ronnn'rs, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Portable Bathtubs and Heaters, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to portable bath tubs and water tank therefor, and its obj eot is to provide a portable tub that may be folded to small compass and inclosing the tank or extended for use. The principal feature of the invention resides in the provision of a platform supported on casters and adapted to be moved readily from place to place and a framework supported on the platform and carrying a water tank and heater therefor adapted for vertical movement in the framework and attached to an end of the tub whereby when the tub is folded the heater is drawn downward to position to be inclosed within the hollow body of the tub and when the tub is extended to elevate the tank, and another object of the invention is involved in the manner of support of the tub in the framework allowing it to be turned from horizontal to vertical position against the said frameworkand so arranged that the rear edge of the tub to which the tank is hingedly connected moves in a vertical plane while being turned. These objects and the several novel features of construction are hereinafter more fully described and claimed and shown in the ac:

companying drawings in which- Figure 1 is a perspective view of a portable tub embodying my invention.

Fig. 2 is a side elevation thereof showing the tub in position for use.

Fig. 3 is a side elevation showing the tub when folded to upright position.

Fig. 4 is a rear end view of the tub show ing the framework and mode of connection of the tank to the tub.

Fig. 5 is an enlarged section taken on line w-w of Fig. 4 showing the construction of the framework to support the tank frame and the guideways for the rollers connected to the rear end of the tub.

The platform 1 is comparatively short in length and is: supported on several casters 2, 2, etc., and at the rear edge is provided an upright framework 3 corresponding to the shape of the upper rim of the tub and against. which the tub closes when folded. The side members 3 and 8 of the frame have a vertical groove 4 in the edge thereof and a second frame 5 is slidably positioned between these two uprights being provided with a tongue 6 riding in the grooves of the uprights on opposite sides respectively. Supported on this frame 5 is a water tank 7, and a burner 8 is supported beneath the tankin any approved manner as by the conduit 9 leading from the oil supply tank 10 above the tan The water tank is also provided with a spigot 11 by means of which the water from the tank may be discharged into the tub 12 therebeneath.

The tub 12 is preferably of sheet metal and comparatively light in weight provided with feet 13 nearthe outer endof a character adapted to rest upon the surface of the floor. At theinner end, the tub is provided with feet 14 provided with casters which ride in arcuate track members 15 secured to the platform, and the length of the feet 13 and 14 is such that, when in the extended relation as shownin Fig. 1, the tub stands in. horizontal position. The tub is provided with anoutlet to which is attached a hose 16 by means of which the water may be discharged, there being provided the usual cover plate for the water outlet for the tub (not here shown). The rim of the tub at the rear end, as shown more particularly in Fig. .5, and upon opposite sides of the rim is providedwith the rollers 17 as shown, and vertical guideways are provided at the lower end of the frame members 3 and 3 as indicated-at 18 which are substantially U shaped in form with the rollers engaging therein against the forward leg of the; U which pro vides-a vertical guide piece for the rollers.

With the tub in position shown in Fig. 2 these rollers are near the upper end of the members 18, and on turning to upright position as shown in Fig. 3, these rollers ride down the vertical guideways and the casters on the legs 14 of the tub ride out on the arcuate tracks 15 therefor. By this arrangement the rear edge of the tub is made to move in a vertical plane, and the tub is thus not fixedly pivoted at any point to the framework. By this arrangement the tub is more readily raised to an upright position than would be the case if actually pivoted at a fixed point, and an object of this invention is secured by this arrangement which enables the end of the tub to be rolled on the tracks to an upright position.

The frame 5 of the water tank 7 is connected with the rear edge of the tub by means of hinge members 20 and 20 adja cent the edge of the tub and tank frame respectively. This hinge connection allows the straps to turn about a pivot as the tub is moved from horizontal to vertical position, and in so moving the tub from the position in Figs. 1 or 2 to position shown in Fig. 3, the tank 7 and oil supply tank 10 mounted thereon and carried by the frame 5 is moved downward in the frames 3 to position to be covered by the tub when brought against the framework. This is necessary for the reason that the oil supply tank and water tank, when the tub is extended as shown, occupies a position somewhat higher than the framework and, by moving the same downward in the framework when the tub is raised, the parts are in position to be inclosed Within the tub, and when the tub is so raised as is shown in Fig. 3, the entire apparatus is readily portable by reason of being carried wholly by the platform 1 and is thus at all times ready for use by simply turning the tub down to horizontal position.

From the foregoing description, it is believed evident that the device is comparatively simple in construction and readily operated after the manner described and when not in use is folded to comparatively small compass occupying but little space. The tub is also particularly adapted for use in isolated places, or residences unsupplied with public water systems, or fixed plumbing.

Having thus briefly described my invention, what I claim is- 1. A portable bath tub and heater comprising a movable platform, a vertical framework thereon having the shape of an in verted U, a second frame movable vertically in said U-shaped frame, a water tank and heating unit supported thereon, vertical guideways provided at the lower end of each side of the said vertical framework, a bath tub, rollers supported on opposite sides of the tub at the rear end engaging the vertical guideways, casters provided at said end of the tub, arcuate tracks provided on the platform for the said casters in which the casters ride as the tub is moved from vertical to horizontal position, and a hinged connection between the Water tank frame and the rear end of the tub.

2. In combination, a bath. tub, a platform, casters therefor, a vertical frame thereon corresponding in outline to the outline of the rim of the tub, a tub having the rear end. supported on the platform, feet for the rear end of the tub provided with casters, feet at the forward end of the tub adapted to rest upon the floor, arcuate tracks on the platform extending in an upward curve therefrom and providing a support for the tub casters, vertical guideways provided on the vertical frame at the lower end, rollers at the rear end of the rim of the tub engaging in the vertical guideways, the said tracks on the platform having a shape correspomling with the path of movement of the casters when the tub is turned from horizontal to vertical position, a water tank and heating unit movable vertically in the vertical frame, and a hinged connection between the rear end of the tub and the said tank whereby turning of the tub causes movement of the tank.

3. In a portable bath tub, a platform mounted on casters, a frame thereon having vertical guideways, a tub, rollers at the rear end and at opposite sides of the rim of the tub engaging in the guideways, casters provided at the rear end of the tub to support the same, tracks on the platform for the casters. the tracks extending in an upward curve from the platform and supporting the casters on turning the tub from vertical to horizontal position in which turning the rollers traverse the vertical guideways, the center of gravity being on a line between the casters and said rollers when the tub is in vertical position.

In testimony whereof, I sign this specification.

RANEY J. ROBERTS.
